Roofing plays an important role in sealing and waterproofing all homes. Dwell Home Venice features intensive and extensive green roofs in addition to standard built-up roofs. The installation of roofing materials requires integration with other building trades such as exterior wall waterproofing materials and also coping on the top of parapets, and so, on this project the roofing was completed in phases.
Tyvek wrap and flashing seals the joint between a window and the wall of the front office. Caulking is placed on the interior. Eventually the entire home will be wrapped in Tyvek.
Versiflex PVC roofing was selected primarily for its cost-effective durability. Versiflex has three layers—a PVC polymer bottom ply, a polyester-reinforced fabric scrim, and a tough thermoplastic PVC-compounded top ply. For warranty purposes it is important that the material is installed according to manufacturer guidelines. Experts at JT Harris installed the roofing system at Dwell Home Venice.

An example of a vent penetrating the roof surface. The penetration is sealed so no water can leak into the house. These important details are often invisible to most occupants of buildings.
A roof installer from J.T. Harris finishes installing the Versico PVC membrane on a garage roof parapet. The parapet will have a black metal coping installed as the final finish.
The bridge from a guest bedroom to the media room will be an Intensive green roof. The width between the parapets will be filled with soil for planting. On the right a drainage scupper needs to be installed and then the PVC membrane will seal the area.
